What are radicals? A radical is an expression that expresses
the square roots, cube roots etc. The following are examples of radicals:

Simplifying Radicals We say that a square root radical is
simplified, or in its simplest form, when the radicand (the number inside) has no square factors.
The following are examples of radicals in simplest form: , 2,
The following are examples of radicals in simplest form: , 3, 2
How do we simplify radicals? STEP 1: Find the prime factors of the radicand.
Try these:
How do we simplify radicals? STEP 1: Find the prime factors of the radicand.
Try these:
1. = 2. = 3. = 4. =
5. = 6. = 7. = 8. =
How do we simplify radicals? STEP 2: For each pair of same prime factor, send
it outside the radical.
